DATA TRANSFER PROCESS USING ADAPTIVE NOISE-IMMUNE CODING Russian patent published in 2007 - IPC H04L1/20 

FIELD: communications engineering, transfer of digital data protected by noise-immune code, including by noise-immune concatenated code.

SUBSTANCE: source information is coded on sending end of communication channel with noise-immune concatenated code (NICC); on receiving end NICC is decoded, and minimal code distance of the latter desired for its correct reception is found from results of decoding; then NICC variables affording this minimal code distance are chosen, NICC variables are changed considering their values obtained when receiving pre-transmitted NICC, and these NICC variables are transferred to sending end; NICC decoding results are used to calculated RMS value of NICC code distance minimal deviation and RMS deviation of its binomial distribution; variations in NICC variables are determined as function of difference between RMS deviation of minimal code distance and RMS value of its binomial distribution.

EFFECT: enhanced noise immunity in data reception through communication channel.
